使用 ARM 模板将 Web 部署到 Azure Functions 失败并出现 ERROR_INSUFFICIENT_ACCESS_TO_SITE_FOLDER

Question

我正在尝试使用 ARM 模板通过 MSDeploy 部署 Azure Function 应用程序（.NET Core，functions v3），但我几乎每次都遇到此错误。这只是偶尔成功。我的函数应用有 5 个基于计时器的函数，每秒运行一次。我目前正在使用部署槽，当它们位于暂存槽中时，我将我的功能设置为禁用（通过 DisabledAttribute 和槽特定设置）。

我用来部署的 ARM 模板：

{
            "apiVersion": "2018-02-01",
            "name": "[concat(variables('webAppName'), '/staging')]",
            "type": "Microsoft.Web/sites/slots",
            "kind": "app",
            "location": "[resourceGroup().location]",
            "resources": [
                {
                    "apiVersion": "2015-02-01",
                    "type": "Extensions",
                    "name": "MSDeploy",
                    "dependsOn": [
                        "[concat(resourceId('Microsoft.Web/Sites/', variables('webAppName')), '/slots/staging')]"
                    ],
                    "properties": {
                        "packageUri": "[parameters('packageUrl')]"
                    }
                }
            ]
        }

ARM-MSDeploy Deploy Failed: 'Microsoft.Web.Deployment.DeploymentDetailedUnauthorizedAccessException: Unable to perform the operation ("Delete File") for the specified directory ("D:\home\site\wwwroot\bin\MyAssembly.dll"). This can occur if the server administrator has not authorized this operation for the user credentials you are using.

如何阻止此错误发生？

类似问题请参考this线程。

您需要添加appOfline参数并将其设置为true，如this文章中所述

    {
  "apiVersion": "2016-08-01",
  "name": "MSDeploy",
  "type": "Extensions",
  "properties": {
    "packageUri": "https://storage.blob.core.windows.net/artifacts/package.zip",
    "appOffline": true
  }

希望以上内容有助于解决您的问题。
